Вопрос:
В случае изменения он выдает org.hibernate.NonUniqueObjectException . В моем классе BidderBO
@Override
@Transactional(propagation=Propagation.REQUIRED, rollbackFor=Exception.class)
public boolean updateBidder(BiddersDetailForm bidderDetailForm, MISSessionBean misSessionBean) throws MISException {
boolean status = false;
boolean childStatus =false;
try {
BidderHeaderBean bidderHeaderBean = populaBidderHeaderBean(bidderDetailForm);
MISAuditBean misAuditBean = new MISAuditBean();
misAuditBean.setStatus(MISConstants.MASTER_STATUS_VERIFIED);
misAuditBean.setEntBy(misSessionBean.getEnteredBy());
misAuditBean.setEntDate(misSessionBean.getEnteredDate());
bidderHeaderBean.setMisAuditBean(misAuditBean);
status = bidderHeaderDao.updateBidderHeader(bidderHeaderBean);
if(status){
long bidderInfoId = bidderDetailForm.getBidInfoId();
List<BidderDetailBean> bidderDetailBeans = populateBidderDetailBeans(bidderDetailForm, bidderInfoId, misSessionBean, MISConstants.MASTER_STATUS_VERIFIED);
log.debug("nBidder DetailBeanst" bidderDetailBeans);
for(BidderDetailBean bidderDetailBean:bidderDetailBeans ){
log.debug("bank name ===========" bidderDetailBean.getBankName());
log.debug("bid amount ===========" bidderDetailBean.getBidAmount());
log.debug("getBidderName ===========" bidderDetailBean.getBidderName());
log.debug("getBidInfoId ===========" bidderDetailBean.getBidInfoId());
log.debug("getSeqBidId ===========" bidderDetailBean.getSeqBidId());
log.debug("status ===========" bidderDetailBean.getMisAuditBean().getStatus());
log.debug("bid sale date ===========" bidderDetailBean.getMisAuditBean().getEntDate());
}
childStatus = bidderDetailDao.updateBidderDetailBeans(bidderDetailBeans);
if(!childStatus){
throw new MISException(MISExceptionCodes.MIS003, "Bidder Details are not updated for " bidderDetailForm.getTenderId());
}
}
} catch (DataAccessException e) {
log.error(e.getLocalizedMessage(),e);
throw new MISException(e.getMostSpecificCause());
} catch (MISException e) {
log.error(e.getLocalizedMessage(),e);
throw e;
}
return status amp;amp; childStatus;
}
и компонент (BidderDetailBean) является
public class BidderDetailBean implements Serializable {
/**
* Initial Version
*/
private static final long serialVersionUID = -2234569083113434751L;
@Id
@GeneratedValue(generator = "seq_bid_id", strategy = GenerationType.AUTO)

@Embedded
private MISAuditBean misAuditBean;
public long getBidInfoId() {

}
public void setBidInfoId(long bidInfoId) {
this.bidInfoId = bidInfoId;
}
public String getBidderName() {
return bidderName;
}
public void setBidderName(String bidderName) {
this.bidderName = bidderName;
}
public Date getBidSaleDate() {
return bidSaleDate;
}
public void setBidSaleDate(Date bidSaleDate) {
this.bidSaleDate = bidSaleDate;
}
……………………………
и BidderHeaderBean есть …..
public class BidderHeaderBean implements Serializable {
/**
* Initial Version
*/
private static final long serialVersionUID = 6163541390640145180L;
@Id
@SequenceGenerator(name="seq_bid_info_id", sequenceName="prwss_main.seq_bid_info_id")

@Column(name="bidding_phase")
private int biddingPhase;
@Column(name="bid_opening_date")
private Date bidOpeningDate;
@Column(name="reference_tender_id")
private String referenceTenderId;
@Embedded
private MISAuditBean misAuditBean;
@OneToMany(targetEntity=BidderDetailBean.class, fetch=FetchType.EAGER)
@JoinColumn(name="bid_info_id", insertable=false, updatable=false)
private Set<BidderDetailBean> bidderDetailBeans;
public long getBidInfoId() {
return bidInfoId;
}
public void setBidInfoId(long bidInfoId) {
this.bidInfoId = bidInfoId;
}
и в моем классе daoimpl я использую эту функцию……..
@Override
public boolean saveOrUpdateBidderDetailBeans(Collection<BidderDetailBean> bidderDetailBeans) throws DataAccessException {
try {
System.out.println("bidderDetailBeans----in dao====" bidderDetailBeans.toString());
getHibernateTemplate().flush();
getHibernateTemplate().saveOrUpdateAll(bidderDetailBeans);
getHibernateTemplate().flush();
getHibernateTemplate().clear();
} catch (DataAccessException e) {
throw e;
}
return true;
}
пожалуйста, дайте какое-нибудь руководство, я также пробовал очистить функцию и объединить и сохранить обновление, но это не работает.
выдает ошибку…………

Ответ №1:
Это исключение возникает всякий раз, когда вы вызываете saveOrUpdate (что означает вложение объекта сеанса) для объекта, который ранее был присоединен к текущему сеансу.
Обходным путем является использование merge, которое присоединяет объект, только если он еще не присоединен, и в этом случае он просто объединяет уже присоединенный объект с текущим объектом, заданным в качестве параметра.
BidderHeaderBean имеет не вставляемую / обновляемую дочернюю ассоциацию:
@OneToMany(targetEntity=BidderDetailBean.class, fetch=FetchType.EAGER)
@JoinColumn(name="bid_info_id", insertable=false, updatable=false)
private Set<BidderDetailBean> bidderDetailBeans;
который не является отображаемым или обратным. BidderDetailBean также не имеет связи с BidderHeaderBean, поэтому эта связь никогда не может работать, поскольку внешний ключ никогда не будет вставлен / обновлен.
Комментарии:
1. На самом деле я использую saveOrUpdateAll, а не saveOrUpdate, и я также использовал merge, но он выдает org.hibernate. Исключение MappingException: неизвестный объект: java.util. ArrayList
2. Это исключение не может быть объяснено вашими текущими сопоставлениями, поскольку там нет ArrayList .
